I picked one up from the clearance aisle at Hobby Lobby years ago for $7.50. The “regular” price was $27.99, but no one buys a kit there unless it’s 40% off.
The one in the kit is the VSS Enterprise. This is the one that crashed in 2014 killing one of the crew. The curret one is the VSS Unity. It seems to have a different colour scheme on the vertical surface as well as a different serial and the name.
It will be interesting to see what the service life ends up being for a composite aircraft flying at altitudes where UV exposure is going to be much greater. Composites don’t usually react well to prolonged UV exposure.
Good grief, the wingspan would work out to 32" at 1/144 scale! I would like a Proteus in 1/72 myself. I had started a Boomerang, but my lack of skills foiled me. Maybe that will be another resurrected build in the future.
